# ShEx.ex

[![CI](https://github.com/rdf-elixir/shex-ex/workflows/CI/badge.svg?branch=master)](https://github.com/rdf-elixir/shex-ex/actions?query=branch%3Amaster+workflow%3ACI)

[![Hex.pm](https://img.shields.io/hexpm/v/shex.svg?style=flat-square)](https://hex.pm/packages/shex)

An implementation of the [ShEx] specification in Elixir.

It allows to run validations specified in the Shape Expressions language (ShEx) on RDF graphs.

> Shape Expressions (ShEx) is a language for describing RDF graph structures. A ShEx schema prescribes conditions that RDF data graphs must meet in order to be considered "conformant": which subjects, predicates, and objects may appear in a given graph, in what combinations and with what cardinalities and datatypes. 

-- [Shape Expressions (ShEx) Primer](http://shex.io/shex-primer/#tripleConstraints)

The validation of larger amounts of nodes is done in parallel.

The API documentation can be found [here](https://hexdocs.pm/shex/). For a guide and more information about ShEx.ex and it's related projects, go to .

## Limitations

- the following ShEx features are not implemented yet:

    - invalid shape expression references in negations are not checked

    - imports

    - external shapes

    - annotations

    - semantic actions

- greedy matching

- non-ascii characters in regular expressions are not fully supported yet
